Brown-Séquard syndrome associated with brachial plexus injury in neck trauma.

A case of adult cervical trauma that resulted in a clinical picture of Brown-Séquard syndrome and unilateral brachial plexus injury is presented. Rotational hyperflexion of the cervical spine is thought to have resulted in subluxation of C5-6 with root avulsions, leading to this unusual combination of findings.

Osteoradionecrosis of the skull stimulating bone metastases.

Multiple skull erosions which simulated bone mestatases developed in a 54-year-old patient who had been treated for favus by radiotherapy 40 years earlier. Radiation necrosis should be recognized and differentiated from defects and erosions due to malignant or infectious process in order to prevent unnecessary procedures and treatment.

Intracranial neoplasms in children: the effect of computed tomography on age distribution.

In a review of all children with brain neoplasms evaluated at a large pediatric center during a three-year period following the introduction of computed tomography (CT), a change was observed in the age distribution at the time of clinical presentation as compared with a previous series evaluated prior to the introduction of CT. In children under six years of age, there was a highly significant trend for earlier diagnosis; within this age group, relatively more children were diagnosed in the first two years of life. Between six and twelve years of age, there was no change in frequency of brain tumor diagnosis between the two series. Above age twelve, there was again noted a highly significant increase in detection of brain tumors in the more recent series. These differences between the two series may be attributed, at least in part, to earlier referral and diagnosis since the advent of CT, although other factors cannot be excluded as possible causes of the differences.

Spinal intradural lipoma with intracranial extension.

2 cases of intradural spinal lipomas with extension into the posterior fossa in infancy are presented. Clinical features included associated subcutaneous posterior spinal lipomas and hypotonia. The cases were diagnosed by metrizamide myelography and spinocranial computerized tomography scanning. Operative therapy consisted of combined suboccipital craniectomy, spinal laminotomy, flap elevation and subtotal tumor decompression. The entity is reviewed.

Delayed epidural hematoma demonstrated by computed tomography: case report.

A case of delayed visualization of an acute parietal epidural hematoma by computed tomography (CT) in a child is presented. The initial CT 21/2 hours after injury was negative. After neurological deterioration, a repeat CT scan 8 hours postinjury demonstrated a parietal epidural hematoma and a small cerebellar hematoma. The case demonstrates the need for a high level of vigilance in head trauma patients even in the face of an initially negative CT scan.

Gliomas of the intracranial anterior optic pathways in children. The role of computed tomography, angiography, pneumoencephalography, and radionuclide brain scanning.

Twenty-two gliomas of the anterior optic pathways in children were reviewed, and the relative merits of computed tomography (CT), pneumoencephalography (PEG), angiography, and radionuclide brain scanning were assessed. Contrast-enhanced CT scans proved to be superior in demonstrating the full extracranial extent of the lesions and spread along the optic pathways; however, PEG was more reliable with small chiasmatic lesions. Angiography rarely provided a specific diagnosis of intracranial optic glioma, but in was diagnostic when the intracanalicular or intraorbital portion of the optic nerve was involved. A protocol for neuroradiological investigation of suspected cases is proposed.

Intracranial esthesioneuroblastoma associated with unilateral visual loss. Case report.

Esthesioneuroblastoma is a rare tumor that arises from the olfactory mucosa and presents usually as a mass in the nasal cavity. Neurological complications occur in about 20% of these cases. Nine cases have been recorded so far in which the neoplasm manifested initially as an intracranial mass. These cases are reviewed and another patient, presenting with progressive unilateral visual loss, is reported.

Evaluation of lateral neck masses by ultrasound and other modalities.

Ultrasound and other modalities were used to evaluate lateral masses in the neck in 26 patients. Accurate diagnosis of solid and fluid-filled masses, both with and without pulsatile components, was achieved through ultrasound studies. Computed tomography was particularly helpful in cases with bone involvement.

Computed tomography of the orbit with special emphasis on coronal sections.

Computed tomography (CT) is an extremely valuable noninvasive method for evaluating orbital soft-tissue structures. The possibility of scanning in the coronal plane has added a new dimension to the study. Direct enlargement viewing of scans on the display console has disclosed minute anatomic and pathologic details.

Orbital fracture evaluation by coronal computed tomography.

Coronal computed tomography produces orbital scans in a plane that is analogous to Caldwell-view x-ray films. Coronal computed tomography permits simultaneous visualization of the orbital walls and the orbital soft tissues, including all extraocular muscles. Using coronal computed tomography, we studied a series of patients with radiographically proven orbital floor fractures. We studied in detail three of these patients, one with a linear orbital floor fracture, one with a depressed orbital floor fracture, and one with a severely comminuted orbital floor. In two patients, coronal computed tomography showed inferior rectus muscle entrapment, which was confirmed at the time of surgery. In each patient, some bone fragments could be seen more discreetly on coronal computed tomography than on conventional polytomes. Coronal computed tomography may be used to help confirm extraocular muscle entrapment in patients with orbital floor fractures. Coronal computed tomography can also be used to examine patients with possible intraorbital foreign bodies, unexplained reduction of vision, or severely displaced bone fragments.

Computed tomography of the orbit with special emphasis on coronal sections: Part I. Normal anatomy.

Computed tomography (CT) of the orbit is capable of demonstrating soft tissue structures not visualized yet by any other radiological modality. The possibility of obtaining direct coronal slices has added a new dimension to the study. Direct enlargement viewing on the display console reveals many anatomical details. For better evaluation of pathological findings, an accurate anatomical knowledge is required. The purpose of this study is to report on the normal anatomy of the orbital soft tissues made visible by CT, with emphasis on the coronal views.

Computed tomography of the orbit with special emphasis on coronal sections: Part II. Pathological anatomy.

Visualization of orbital soft tissue structures by computed tomography in direct coronal and axial studies is extremely useful in diagnosis. Direct enlargement viewing of scans has disclosed minute anatomical details. This study reviews some of our experiences in the investigation of a variety of lesions within the orbit and attempts, in particular, to illustrate the value of direct coronal studies.

Computed tomography in primary malignant lymphoma of the brain.

Primary malignant lymphoma of the brain is a rare lesion characterized clinically by varied nonspecific neurologic deficits and usually a rapid fulminant deterioration and death. This course may be altered by radiotherapy, and early diagnosis assumes major importance. Laboratory tests, EEG, radionuclide scans, angiography, and pneumoencephalography may not show definite abnormality in the early stages. This report concerns four cases in which good correlation between the location of the brain lesion and the abnormality on computed tomography scan was demonstrated.
